for CASSANDRA-19151
- TransactionStatement token aware routing
- Mitigate convoy effect:
- ExecuteTxnBacklog v1 can execute single key transaction backlogs and disseminate the result
- Direct local execution possible for single key transactions
- Use shardAppliedBefore instead of gcBefore to cleanup CFK faster
Also Improve:
- Introduce distributed tracing
- Combine RejectBefore and MaxConflicts
- Self-addressed messages are delivered directly
- Disable AccordSyncPropagator by default, as incompatible with large clusters
- FastPathStrategy.SIMPLE should not modify fast path contents; FastPathStrategy.UP introduced to adopt this behaviour
- Configurable queue prioritisation
- ProtocolModifiers mostly final
- Remove unnecessary condition check when serializing TxnUpdate
Also Fix:
- SequentialExecutor ownership bug
- BTree.XUpdater.reset()

use compression ratio to scale the amount of remaining disk usage
CompactionInfo::estimatedRemainingWriteBytes is uncompressed, causing compaction to be rejected due to size when it has space to complete

SinglePartitionReadCommand.Group#create - typical single partition select, use singletonList instead of ArrayList + Object[]
SelectStatement#getSliceCommands - remove unnessesary cloning of partition key, it is a part of a very old patch, now we copy all values from Netty buffers
SelectStatement#getSliceCommands - typical single partition select, use singletonList instead of ArrayList + Object[]
SinglePartitionReadQuery.Group#maybeValidateIndex, avoid iterators for restrictionSet if a full partition is selected

Best effort attempt to get tableId from CFS, fallback to null which
still allows snapshot to be loaded
End result is that nodetool clearsnapshot and listsnapshot function for such
snapshots on restart
In addition to 5.0 patch we move starting SnapshotManager to after TCM is initiliazed.
The consequence of such a move is that cleanup of ephemeral snapshots happens after startup checks pass.

With negotiated authentication (CEP-50), nodes may be configured with multiple authenticators. Prior to this change,
a number of areas in the code assumed that there was a single configured authenticator and contained logic that
switched depending on the authenticator type. This logic won't work when multiple authenticators can be configured.
This change eliminates most calls to DataDescriptor.getAuthenticator(), by enabling individual authenticators to
declare the role attributes they support, requiring callers to specify the type of authenticator they're looking
for, and directly returning whether the node can enforce authn or not rather than inferring it by the presence of
an authenticator.
Testing done: Unit tests for auth and config packages; d-tests for auth-related functionality (e.g. ColumnMasks).

The same idea was applied previously in UnfilteredSerializer#serializeRowBody. A state is passed into a consumer function using the existing helper object.
